I'm willing to bet that almost all public seating options aren't as eco-friendly as the Rainwater Pipe Bench. This bench was designed by OneTwo out of odds and ends of rain pipes.
Almost everything made produces scraps. Most scrap parts are thrown away when they could be upcycled into something awesome like the Rainwater Pipe Bench. Keeping scraps, especially plastic ones out of landfills, could easily be accomplished with innovative designs like those of OneTwo.
